AGRICULTURAL MACHINE.

Specification of Letters Eatent.

Application filed October 30, 1912. Serial No. 728,716.

To all whom it may concern.'

Be it known that we, VILLIAM R. Annoor. and Josera TV. Lnrinn, citizens ot1 the TCnitcd States. residing at Lafourche Crossing, in the parish of Aiiafourche, State ot Louisiana, have invented a new and useful tigriculturaA Isla/chine, of which the following is a specitlcation. l

This invention relates to agricult iral inachiiics and more particularly to a novel form of tractor designed for use in the cultiration oil?. sugar cane and sorghum at all stages of thc growth thereof.

One ot the objects oj the invention is to provide a tractor having high arched axles so proportioned as to straddle the rows at different stages of the groi 1 'he plants,

here being means combined .v Ior whereby the plants may be i t draining ditches may be producen gacent the rows.

lilith the foregoing and other objects uwi view which will appear as the descrip proceeds, the invention resides in the bination and arrangement of parts and in the details ot construction hereinafter described and claimed, it being understood that changes in the precise embodiment ci' the invention herein disclosed, can be made within the scope of what is claimed, .without departing from the spirit ot the invention.

in the accompanying drawings the preferred iorm oi? the invention has been shown. Aln said drawingsz-Figure l is a side elevation ot the machine. Fig. Q is a. rear elevation thereof. Fig. 3 is a transverse section through the frame of 'the lmachine and showing the front axle in elevation. Fig. 4; is a plan view of the rear portion of the machine. the platform and the mechanism supported thereby being removed.

teferiing to the gures by characters .ozt'

reference l designates the arched front axle of the machine and 2 designates the arched rear axle thereof, the axle l beingsupported.

by wheels 3, while the axle 2 is supported by drive wheels 4.

The frame ot the machine has been indicated at 5 and is mounted tixedly upon the arched axle 2 and extends over the axle l, to which it is connected by means ot a king bolt 6. The front end of the frame is supported at its center above the axle l by bearing blocks 'l' and these blocks permit the axle l to swing laterally relative to the traine so as lthus to be capable of' traveling over an uneven surface without either tilting or distorting the front end of the traine. l

E( ch oli' the drive wheels has a sprocket 8 secured thereto and these sprockets receive motion. through chains 9, from smaller sprockets 10 secured to a shaft ll which extends 'transversely of the traine. A motor, which` has been indicated generally at l2. is mounted on. the front portion ot the 'trame and suitable mechanism, such indicated generally at i3, is provided for transmitting motion from the motor to the shaft l1. inasmuca as this power trans mittiugn mech n sin constitute-s no part of the present s. ent-ion. it is not deemed necessary 'to describe and illustrate the saine in de iil.

are arranged upon the side tions of the arched axle l and journaled L'iin them ariy knuckle members 1.3 having ymtstanding spindles on which the wheels 3 are journal/ed. in arm 16 extends rearthese larms arc secured to the ends of a chain 17 which extends partly around guide sheaves i8 and engages a sprocket 19 attac to the lower end ot' a shaft 20. This shaftl extends upwardly within the c lrom each knuckle member l5 and frame and is provided with a steering wheel Thus it will be seen that by rotating wheel 2l, chain 17 can be actuated so as to swing the arm 16 to the right or to the lett and thus guide the machine while in operation.

Connected to a cross beam 22, secured in and i'orining a` part of the frame 5, is a hanger 23 to which a coupling plate 24; is

pivotally connected so as to swing in a fg substantially vertical plane. rThis coupling plate has a tongue E25 at one end which may be pivotally engaged by a forked extension 26 formed at the center of the front end of a traine 27. As shown in the drawings, this frame extends downwardly and rearwardly and its terminals engage the side portions or" a yoke 28. Each end of the yoke is provided with a gang of cultivator disks connected thereto in any suitable lmanner, the two gangs of disks being spaced apart so that said gangs will travel along opposite sides of a row. Chains 30' or other suitable connections extend upwardly from the sideport-ions of the yoke 2S and are attached to spools 3l secured to a shaft 32. This shaft is mounted upon the trame 5 and. extends transversely ot the rear end portion thereof and a hand wheel 33 is secured to the shaft and by means ther-cotl the sha'tt can be rotated so as to wind the connections 30 upon the spools 3l. Thus it will be seen` that the gangs of cnltivator disks 20 can be raised and lowered as desired.

For the purpose ot digging ditches along' the sides of the rows being cultivated, gangs of plows are mounted in a novel manner back oi the drive wheels 4 ot the machine. rlhis is done by mounting inner and outer side strips 34 and 35 upon the end portions of a bolt 3G which extends through each spindle 37 o't' the rear axle i2, the strips bcing detachably secured to the bolt. in any suitable manner and being likewise held together back of the wheels 4 hy means of cross strips 3S. Extending downwardly from each side strip 34 and 35 is a standard 39 and secured to these standards is a single moldboard plow 40. Another standard 4l extends downwardly from the rear cross strip 38 and from the rear ends of the cross strips 34 and 35 and a double moldboard plow 42 is secured thereto. The-plows 40 in each group aredesigned to turn the furrow slices to the right and left respectively and the double moldboard plow following them operates to throw the soil to both sides from the center of the furrow pro* duced by the three plows of the group. As shown particularly in Figs. 2 and 4, the double moldboard plows are disposed di-o rectly back of the Wheels 4.

It will be apparent'that the side strips 34 and 35 and the cross strips 38 form a trame designed to swing about the bolt 36 as a pivot. Connected to each of these frames is a lifting bar 43 the upper end of which is attached to one arm of a bell crank lever 44 carried by the frame 5. Any suitable means, such as a toothed segment 45 and a spring pressed pawl 4G, may be employed for locking the bell crank lever against movement. l

It will be understood that. when the machine is driven forward, the axles l and 2 vtherewith.

will straddle the row to be cultivated.. At the saine time the gangs ot' disks QS) will cultivater the soil close to the sides ot' the row and the plows 40 and will dig deep turrows along the sides of the row and' which constitute means for draining the rows. The eultivator disks can be readily elevated by means of wheel 33 and spools 3l. and the plows can also be raised or lowered by manipulating the lever While the machine has been shown provided with eultivator disks ditching' plows it is to be understood that other "formsy l :oil engaging devices may be employed in lieu thereof or inl con'ibination For example, instead ot' connecting the disks QS) to the center of the machine, as shown, a plow of any suitable type can be arranged under the frame 5 and its beam coupled to the plate 24. This construction is so obvious that it is not deemed necessary to illustrate it.

Vhat is claimed is An agricultural machine including a Jrear arched axle, propelling wheels supporting the same, a trame straddling eaeh'of the wheels and mounted to swing about that portion of the axle engaged by the wheel, soil engaging devices carried by the frame for loosening` the soil depressed by the wheel, levers, a non-'fi'exible connection between each lever and one ot'the frames, said lever and connection constituting means for forcing the soil engaging devices into the soil, means for loclingkthe lever against movement, a yoke interposed be-v tween the frames, soil engaging devices carried thereby, and means for. raising and lowering the yoke, said yoke and the frames vbeing separately adjustable upwardly and downwardly7 the yoke being adapted to swing laterally between the frames. l In testimony that we claim the foregoingl as our own, we have hereto atlixed our signatures inthe presence of two witnesses WILLIAM ROLAND ARBOUR. JOSEPH VILSON LEPINE.
